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?
Reference Exercise 21
A student in the laboratory connects a 10- ? resistor, a 15- ? resistor, and a 20- ? 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?
