PHYSICS HOMEWORK PLEASE HELP !!
(a)
Let the equivalent resistance of the circuit when the switch is open be
Req, open,
and the equivalent resistance when the switch is closed be
Req, closed.
Find the difference (in Ω) between the two equivalent resistances,
Req, open − Req, closed.
(b)
When the switch S is closed, the equivalent resistance drops to 58.0% of the original value. Determine the value of R (in Ω).
(c)
What If? What would the voltage (in V) between points a and b have to be for 130 W to be delivered to the circuit when the switch is closed? Assume that R has the value found in part (b).
