(a)
Interpretation:
The voltage V2 should be calculated.
Concept introduction:
When resistors are in series, a voltage divider. V = V1 + V2 + V3
The current in a series circuit is everywhere the same. In other words, I = I1 = I2 = I3
The total resistance Rs of a series circuit is equal to the sum of the resistances of the individual components. Rs = R1 + R2 + R3
Ohm’s law;
Ohm’s law describes the relationship among voltage, resistance, and current in a resistive series circuit.
V = IR
(b)
Interpretation:
The power loss in resistor R2 should be determined.
