Question

A variable resistor Ro is connected across the terminals a, b in the circuit in (Figure 1). The variable resistor is adjusted until the maximum power is transferred to Ro. Suppose that vs = 210 V and R = 5.6 k?. Here we learn how to find the power delivered to a load resistor that is set for the maximum power transfer. Part C Find the percentage of the total power developed in the circuit that is delivered to Ro. Express your answer as a percentage to three significant figures. % delivered to Ro = 6.37%

Step 1

We can use the formula P = V^2 / R, where V is the voltage across the circuit and R is the total resistance. Since the circuit is in series, the total resistance is the sum of R and Ro. Given that Ro = 1.87 k-ohms and R = 5.6 k-ohms, the total resistance is 7.47 Show more…
