Given:
The value of each resistance in parallel combination is,
The value of the resistance in series with the parallel resistances is,
The potential drop across the battery is,
To find:
The voltage drop across each 15.0 ohm resistance
Step-by-step explanation:
The value of the equivalent resistance of the three parallel resistances is,
The net resistance of the circuit is,
The circuit diagram is like this:
The current in the circuit is,
The potential drop across 10.0 ohm is,
The potential drop across each of the 15.0 ohm resistance will be the same as the resistances are parallel.
So, the potential drop across each 15.0 ohm is,
Hence, the required potential drop is 15.0 V.
