Question

1. Determine the equivalent resistance of the circuit shown in the figure. (Figure 1). Express your answer to three significant figures and include the appropriate units.

2. Determine the voltage across 820 ? resistor. Express your answer to two significant figures and include the appropriate units.

3. Determine the voltage across 960 ? resistor. Express your answer to two significant figures and include the appropriate units.

4. Determine the voltage across 680 ? resistor. Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

1) R= 1330 ohms

2) current through the circuit is i =V/R =12/1330 =9 .0 ma

so potential across 960 ohm resistor is ix960 = 8.64v

so ptential across 820 ohm = 12 -8.64 = 3.36V

3) voltage across 960 ohms = 8.64 V

4) voltage across 620 ohm = 3.36 V
