V1 I + L M ww R3 S1 Imm LL(t) R1 Figure 5: A circuit S2 12 www R2 Given the circuit in figure 5 with component values R₁ = 20 №, R₂ = 80 N, R3 = 1 kN, L = 3.5 H, V₁ = 5 V, 1₂ = 0.51₁(t). Switch S₁ and S₂ are kept in their current state as shown in figure 5 for the circuit to reach steady state. At time t = 0 seconds, both switches (S₁ and S₂) are toggled. Calculate the current through inductor L for all time.

A moving coil ammeter gives a full scale deflection for a current i = 300 mA and its coil has a resistance RC = 1Ω. To use this ammeter as a voltmeter that measures 9V at full scale deflection a multiplier resistance, RM, is added in series with the coil. What is the value of the multiplier resistance? Select one: a. 31 Ω b. 32 Ω c. 30 Ω d. 29 Ω
