Question

(a) What is the current through each resistor if V3=0V? What direction does the current ?ow in each branch?
(b) What is the power dissipated on each circuit element? How much energy is lost by the 10? resistor in a span of 25 seconds?
(c) What voltage does V3 need to be so that the current through the middle branch is zero?
please help

Analyze the circuit below: (a) What is the current through each resistor if V3=0V? What direction does the current ?ow in each branch? (b) What is the power dissipated on each circuit element? How much energy is lost by the 10? resistor in a span of 25 seconds? (c) What voltage does V3 need to be so that the current through the middle branch is zero? please help

Explanation / Answer

No circuit diagram is displayed

b) Power dissipated on each resistor can be calculated using the formula

P = i2 R                or   P = V2 /R

P = Power , V = Voltage across resistor , i = Current in the resistor

R = value of resistance

to calculate the energy , we can use

Energy = P t ,,           t = time
