ABSTRACT
Figure 7.6 may be redrawn as shown in Figure 7.7, and voltage
V = (
6 6+ 4
) (50) = 30V
Problem 5. Two resistors are connected in series across a 24V supply and a current of 3A flows in the circuit. If one of the resistors has a resistance of 2, determine (a) the value of the other resistor, and (b) the p.d. across the 2 resistor. If the circuit is connected for 50 hours, how much energy is used?
