Jack measured 1 amp as the total current in a certain circuit when he applied 20 volts to the circuit.
Find the resistance of the circuit
R =
R =
R = 20 ohms is the resistance of the circuit
:
When he applied 60 volts, he got a measurement of 3 amps.
I =
I =
I = 3 amps
:
Write a linear equation describing the relation between voltage and current
I =
:
Calculate the total current when 50 volts are applied to the circuit.
I =
I = 2.5 amps
