Key Concepts of Ohm's Law. Ohm's Law states the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = I × R. Voltage (V) is the potential difference that drives current through a circuit. Current (I) is the flow of electric charge, measured in amperes (A). Resistance (R) is the opposition to the flow ...

Perfect for beginners to basic circuit equations. ... Example / Ohm's Law Practice Problems. Problem 1. Node A: 1000V to Node B: 0V, across a 100 ohm resistor.
Two series resistors of resistance 5 ohms and 15 ohms are connected in series. If the voltage drop across 5-ohm resistors is 2.5 V. Calculate current across 15 ohms resistor: 0.5 A; 1 A; 5 A; Insufficient data; Correct answer: 1. 0.5 A. From Ohm’s law: I = V/R = 2.5/5 = 0.5 A. Since both are in series, same current flows across them.
Ohm's law states that the current through a conductor (or resistor) between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, it arrives at the usual mathematical equation I = U/R or I=V/R Direction: Solve each problem carefully and show your solution in each item.
