Question

In the following diagram, the voltage is 1.5 volts and the resistance is 7.5 ohms. Use Ohm's law to determine the current in the circuit.


11.3 amps

5.0 amps

6.0 amps

0.2 amps

Answer 1

Ohm's law is that \[V = IR\]where \(V\) is the voltage, \(I\) is current, and \(R\) resistance. You know \(V\) and \(I\), so solve the formula for \(R\) in terms of the other two and plug in your known values.

Answer 2

Oops, you know \(V\) and \(R\), solve the formula for \(I\) in terms of the other two and plug in your known values :-)
