A 15Ω coffee maker and a 15Ω frying pan are connected in series across
a 120V source of voltage. A 22Ω bread maker is also connected across
the 120V source and is in parallel with the series combination.
1. Find the total current supplied by the source of voltage.

2.Find the power dissipated across the bread maker.
**Help with NUMBER 2 Please**

Solutions

Expert Solution

Resistance of coffee maker

Resistance of frying pan

Resistance of bread maker

(1)

R1 and R2 are in series, their equivalent resistance is

R3 is in parallel with R12, the equivalent resistance of the circuit is

The voltage across the circuit is 120V. So, the total current supplied by the source of voltage is

(2)

Bread maker is directly connected to the voltage source, so the voltage across the bread maker is 120V. The power dissipated by the bread maker is

Using Ohm's law I=V/R
