Three ways to explore the same fundamental relationship. Change any two variables and watch the third respond.
Solve for Voltage (V)
Current Source → Resistor → Ground
V = I × R
100 V
Solve for Current (I)
Voltage Source → Resistor → Ground
I = V / R
1.00 mA
Solve for Resistance (R)
Voltage Source → Unknown R → Ground
R = V / I
1.00 kΩ
