Maximum Voltage for a Voltage Source

What is the maximum voltage for which the voltage source is not supplying power?

Given that current (IS) is 0.13333 A, resistance (R1) is 10Ω, and resistance (R2) is 30Ω, what is the maximum voltage (VS) for which the voltage source is not supplying power?

Answer:

The maximum voltage for which the voltage source is not supplying power is 5.33V.

To determine the maximum voltage for which the voltage source is not supplying power, we can use Ohm's law and Kirchhoff's loop law. When the current through the source is zero, the source is not supplying power.

Given that IS = 0.13333A, R1 = 10Ω, and R2 = 30Ω, we can calculate the voltage drop across each resistor. The voltage drop across R1 (V1) is 1.33V, and across R2 (V2) is 4V.

According to Kirchhoff's loop law, the voltage source VS will be the sum of these voltages (VS = V1 + V2). By substituting the values of V1 and V2, we get VS = 1.33V + 4V = 5.33V.

Therefore, the maximum voltage for which the voltage source is not supplying power is 5.33V.
