I measure a voltage drop of 30mv over a 2.5 ohm resistor. How long will a 3Ah battery last? Write your ansser 'XXX hours'
First, find the current by using Ohm's law (V = IR). Rearrange the formula to find I (current) = V / R. Current = 30mV / 2.5 Ω = 0.012 A Next, find the battery capacity in watt-hours (Wh). Since power (P) = current (I) × voltage (V), and energy (Wh) = power (P) × time (t), you can find the battery's energy capacity in watt-hours by multiplying its current capacity by its voltage. For a 3Ah battery, assuming a typical voltage of 3.7V for a lithium-ion battery, the energy capacity is: Energy capacity = 3 Ah × 3.7 V = 11.1 Wh Finally, to find the time (t) the battery will last, use the formula t = energy capacity / power. In this case, the power is the current (0.012 A) times the voltage drop (0.03 V): Power = 0.012 A × 0.03 V = 0.00036 W Time (t) = 11.1 Wh / 0.00036 W ≈ 30833.33 seconds Convert the time in seconds to hours: 30833.33 seconds ÷ 3600 seconds/hour ≈ 8.56 hours So, the battery should last approximately 8.56 hours. Answer: 8.56 hours

To determine how long a 3Ah battery will last, we first need to find the current flowing through the circuit using Ohm's law (V = IR). Then, we can use the battery's capacity to find the time it will last. Given: Voltage drop (V) = 30 mV = 0.030 volts Resistance (R) = 2.5 ohms Battery capacity (C) = 3 Ah First, find the current (I): I = V / R I = 0.030 volts / 2.5 ohms I = 0.012 amperes (A) Next, find the time (t) the battery will last using the formula: t = C / I Time (t) = 3 Ah / 0.012 A Time (t) = 250 hours So, the 3Ah battery would last approximately 250 hours. Answer: 250 hours.

To find out how long the 3Ah battery will last, we first need to determine the current flowing through the resistor. We can use Ohm's law for that: Current (I) = Voltage (V) / Resistance (R) I = 0.030 V / 2.5 Ω ≈ 0.012 A Now, we can use the battery's capacity to determine how long it will last. The capacity is given in ampere-hours (Ah), which represents the amount of current that a battery can supply for one hour. In this case, the battery has a capacity of 3 Ah. To find out how long the battery will last with a current draw of 0.012 A, we can use the following formula: Time (t) = Capacity (C) / Current (I) t = 3 Ah / 0.012 A ≈ 250 hours So, the 3Ah battery will last approximately 250 hours.

First, let's find the current through the resistor. We can use Ohm's law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R): I = V / R In this case, the voltage drop is 30 millivolts (0.03 volts) and the resistance is 2.5 ohms, so the current is: I = 0.03 volts / 2.5 ohms = 0.012 amps Next, we can use the formula for the capacity of a battery to find out how long it will last. The capacity (C) is equal to the current (I) times the time (t): C = I \* t We can rearrange this formula to solve for the time: t = C / I In this case, the battery has a capacity of 3 amp-hours (3600 coulombs) and the current is 0.012 amps, so the time is: t = 3600 coulombs / 0.012 amps = 300,000 seconds Finally, we can convert the time in seconds to hours by dividing by the number of seconds in an hour (3600): t = 300,000 seconds / 3600 seconds/hour = 83.33 hours So, the battery will last approximately 83.33 hours. XXX hours = 83.33 hours.

To find out how long a 3 Ah (ampere-hour) battery will last, we first need to determine the current flowing through the resistor. We can use Ohm's Law for this: Current (I) = Voltage (V) / Resistance (R) I = 0.030 V / 2.5 Ω ≈ 0.012 A Now that we have the current, we can calculate the time it takes for a 3 Ah battery to provide this current: Time (T) = Capacity (C) / Current (I) T = 3 Ah / 0.012 A ≈ 250 hours So, a 3 Ah battery will last approximately 250 hours to provide a current of 0.012 A in the given circuit.
