Consider the circuit shown in figure (32 - E8). Find the current through the 10 Ω resistor when the switch S is (a) open (b) closed.
figure (32 - E8)
Req=(10+20)Ω=30Ω
i=(330)A=0.1A
Req=10Ω
i=(310)A=0.3A
Consider the circuit shown in figure (32-E19a). Find (a) the current in the circuit, (b) the potential drop across the 5Ω resistor, (c) the potential drop across the 10Ω resistor. (d) Answer the parts (a), (b) and (c) with reference to figure (32-E19b)
