Two 34 Ω and one 54 Ω light bulbs and a 24 V battery are connected in a series circuit. What is the current (in A) that passes through each bulb [round your final answer to two decimal places]?
A student in the laboratory connects a 17 Ω resistor, a 31 Ω resistor, and a 36 Ω resistor in series and then connects the arrangement to a 59-V dc source.
(a) How much current is in the circuit? (b) How much power is expended in the circuit?
Suppose voltage V is applied across a resistance R. The power dissipated in the resistance is P. Now the same voltage V is applied across a parallel combination of three equal resistors each of resistance R. Then the power dissipated in the second case will be
A) P
B) 3P
C) p/3
