Me with this problem. I'm lost. Problem 9: Two resistors are connected in parallel (R1 = 7.5 ohm, R2 = 10.2 ohm) to a V = 9.75 V source. Randomized Variables R1 = 7.5 ohm R2= I0.2 ohm V = 9.75 V Part (a) Input an expression for the amount of charge q which passes through the circuit every second? Expression : q = R1(R2)/(R1+R2) Select from the variables below to write your expression. Note that all variables may not be required. alpha, beta, theta, d, g, h, i, j, k, m, P, R1, R2, t, V Part (b) What is the charge per second in C? Numeric : A numeric value is expected and not an expression. q= Part (c) How much power is dissipated in the circuit in W? Numeric : A numeric value is expected and not an expression. P=

Explanation / Answer

a) Charge passing per second =Current

Req = R1*R2/(R1+R2)

I = V/Req = V * (R1+R2)/(R1*R2) (ans)

b)Charge per second = I*t =I*1=I =  V/Req = V * (R1+R2)/(R1*R2) = 2.26 C (ans)

c)Power = V^2/R eq =22.01 W (ans)
