The student in Exercise 21 repeats the experiment but with the resistors connected in parallel.
(a) What is the current?
(b) What is the power?
Exercise 21
A student in the laboratory connects a 10-Ω resistor, a 15-Ω resistor, and a 20-Ω resistor in series and then connects the arrangement to a 50-V dc source.
(a) How much current is in the circuit?
(b) How much power is expended in the circuit?
