Question

A set of data is collected from a simple circuit with a

20 Ω resistor and is represented in the table.



The current at 5.0 V is
A.

The current at 15 V is
A.

Answer 1

A. Recall Ohm's Law: V = IR

If V = 45 volts, and I = 5 amps, the R = V/I = 45V/5A = 9Ω

B. We know the potential difference and the resistance, both of which have good units. All we have to do is plug the known values into the equation and solve for the current:

I=15V9Ω

Thus, the electric current is: 1.67A
