___________V

b.) A 25 ? resistor has a 39 V drop across it. Determine the current passing through the resistor.
____________A

c.) A resistor has a voltage drop of 56 V when a 7.8 mA current is passing through it. Determine the resistance of the resistor.
___________k?

D) 8081 ? resistor has a 2.83 A current passing through it. Determine the power loss of the resistor.
____________W

A wire has 571 C pass through it in 33 s. Determine the current passing through the wire.
____________A

Explanation / Answer

A) R = 36 ; i = 7A

v = iR = 252 volts

B) R = 25 ; V = 39 v

i = V/R = 1.56 A

C) v = 56 v ; i = 7.8 mA = 7.8 * 10^-3 A

R = v/i = 7.18 * 10^3 = 7.18 K

D)R = 8081

i = 2.83 A

Power = i^2R = 64719.9 watt

charge on wire, q = 571 C

time, t = 33 s

current, i = q/t = 17.3 A
