Determine the total resistance of this series circuit when: R_{1} = 270W R_{2} = 180W

Determine the total resistance of this series circuit when:

R_{1} = 270W R_{2} = 180W

1. State the appropriate equation: R_{T} = R_{1} + R_{2}

1. State the appropriate equation:

R_{T} = R_{1} + R_{2}

2. Substitute the given values: R_{T} = 270 + 180

2. Substitute the given values:

R_{T} = 270 + 180

3. Complete the calculation: 270 + 180 = 450

3. Complete the calculation:

270 + 180 = 450

R_{T} = 450W
