Determine the total power supplied to the two resistors

Reference no: EM13289901

Three resistors are connected in series across a battery. The value of each resistance and its maximum power rating are as follows: 4.0? and 28.6 W, 34.6? and 8.45 W, and 12.3? and 9.65 W.

(a) What is the greatest voltage that the battery can have without one of the resistors burning up?

(b) How much power does the battery deliver to the circuit in (a)? A coffee-maker (18 ?) and a toaster (19 ?) are connected in parallel to the same 120-V outlet in a kitchen. How much total power is supplied to the two appliances when both are turned on?

The drawing shows three different resistors in two different circuits. The battery has a voltage of V = 27 V, and the resistors have resistances of R1 = 50.0 ?, R2 = 25.0 ? and R3 = 10.0 ?. Determine the current through and the voltage across each resistor. Two resistors, 36.9 and 49.9?, are connected in parallel. The current through the 49.9-? resistor is 4.33A.

(a) Determine the current in the other resistor.

(b) What is the total power supplied to the two resistors?
