Question

In the circuit below, R=10.0 ohms, L=30.0 h, and E=20v. switch s1 is closed and switch s2 is left open. After the circuit has reached its final value switch s1 is opened and switch s2 is closed. what is the magnitude of the potential difference between points a and b three seconds after s2 is closed (inV).

7. In the circuit below, R = 10.0 12, L = 30.0 H, and ε = 20.0 V. Switch S1 is closed and switch S2 is left open. After the current has reached its final value, switch S1 is opened and switch S2 is closed. What is the magnitude of the potential difference between points a and b three seconds after S2 is closed (in V)? (A) 3.89 (B) 9.12 (C) 2.00 (D) 7.36 (E) 6.54 (F) 1.00 E Sy Sa b ba mm L R.

please upvote....thank u

for diş changing anuies L-R circuit. V (t) = Voeth Here Vo=20v t = 3 sec R = lor La30H -3x10 2) V (3) = 20v xe 30 20x etv 20 e V 20 2.718 - 7.36 V So potential difference across a and b is 7.36 v. D is correct.
