**EXAMPLE
PROBLEM ON RESISTORS IN SERIES**

**Question**

The current flowing in a circuit containing four resistors connected
in series is **I = 1.0 A**. The potential drops across the first, second
and third resistors are, respectively: **V = 5 V**, **V = 8 V** and
**V = 7 V**.

The equivalent resistance of the circuit is **R = 30**.

Find the total voltage supplied by the battery, and also current, voltage drop, and resistance of each resistor in the circuit. |

**Hints**

- How are resistors related when connected in series?
- What is true about potential drops of resistors when connected in series?
- You will need to use Ohm's Law.
