Question

Henrietta would like to determine the voltage on one of her old batteries. She hooks it up to a circuit with a 330 ohm resister and is able to measure the current on the circuit at 0.1 amps. How many volts is the battery supplying? Round your answer to the nearest whole number (for example if the answer is 41.2 volts, enter 41).

Answer 1

First, let's make a diagram of the situation:

We can use ohm's law in order to find the voltage:

`\begin{gathered} V=IR \\ Where: \\ I=0.1A \\ R=330\Omega \\ so: \\ V=0.1(330) \\ V=33V \end{gathered}`

Answer:

33 V
