Question

True or False 1. When two or more resistors are connected one after another, they are in series. The current going through each one of them is equal. When two or more resistors are connected one after another, they are in series. The voltage difference (potential difference) across each resistor has to be equal. 2. 3. When two or more resistors are connected in parallel, the current going through each one of them must be equal. 4. When two or more resistors are connected in parallel, the voltage difference (potential difference) across each resistor is the same. 5. The equivalent resistance for two resistors in series is equal 6. The equivalent resistance for two resistors in parallel is equal 7·The total voltage drop across two resistors in series is equal to the sum of the two individual resistances. R-R. +R to the sum of the two individual resistances. R R +R to the sum of the voltages across each individual resistance: V= V + V 8. The total current through two resistors in series is equal the current though any ONE of the two resistors. I = I. Because V = V + V, for series case, dividing 1 from each side of the equation leads to: V/-/ 1 + 1 , hence, Re= R +R 9. The total voltage drop across two resistors in parallel is equal to the sum of the voltages across the two individual resistances V= V + V 10. The total current through two resistors in parallel is equal the current though any ONE of the two resistors. I = I. Because AV = AV + V for parallel case, dividing l from each side of the equation leads to. AV/ 1 =AVI + AV. / L hence, R R +R.

Explanation / Answer

1. They are in series and current through each one of them is equal. True

2. Voltage is not equal. False

3. In parallel, current is not equal. False

4.Voltage across each is same . True

5. Equivalent resistance = sum of each resistance, Or, R= R1+R2. True

6. In parallel, Equivalent resistance is not equal to the sum of each resistance. False

7. In series, total voltage drop= voltage drop across individual resistance, Or, V= V1+V2 . True

8. Current through resistors in series is same, and so, R= R1+R2. True

9. Voltage drop in parallel is not the sum of voltage drop across each. False

10. Current through resistors in parallel is not same, so I and I1 and I2 are different and R is not same as R1+R2. False
