• C. An invisible form of energy which reveals itself through the work it does

• D. The chemical reactions which occur only in battery

2. A material that allows electric current to flow under one condition and restrict it under another condition is called

• A. Resistor

• B. Conductor

• C. Semi – conductor

• D. Insulator

3. Which device protects a circuit from harmful overload

• A. Fuse

• B. Resistor

• A. Series circuit

• B. Parallel circuit

• C. Series parallel circuit

• D. Parallel series circuit

5. The formula to look for the total resistance of a parallel circuit resistor is

• A. $RT = R1 + R2 + …. + Rn$

• B. $RT = R1 \times R2 \times ….. \times Rn$

• C. $RT = (R1 + R2) / R1 \times R2$
