1Question

What is electric current?

2Question

A circuit has a voltage of 12 V and a resistance of 4 Ω. What is the current?

3Question

A resistor has a current of 2 A flowing through it and a resistance of 6 Ω. What is the voltage across the resistor?

4Question

Two resistors, 5 Ω and 10 Ω, are connected in series. What is the total resistance?

5Question

A 24 V battery is connected to a circuit with a total resistance of 8 Ω. Calculate the current in the circuit and explain whether this current would increase or decrease if the resistance were doubled.

Answer Key

#	Answer
1	Electric current is the rate at which electric charge flows through a conductor, measured in amperes (A).
2	Using Ohm's law, I = V/R = 12/4 = 3 A.
3	Using Ohm's law, V = IR = 2 × 6 = 12 V.
4	For resistors in series, total resistance is the sum: 5 Ω + 10 Ω = 15 Ω.
5	Current: I = V/R = 24/8 = 3 A. If resistance were doubled, the current would decrease because current and resistance are inversely related when voltage stays the same.
