To determine The voltage across the resistance, R 3 . Explanation Write the expression for equivalent resistance for parallel connection. 1 R = 1 R 3 + 1 R 2 R = R 3 R 2 R 3 + R 2 (I) Here, R is the equivalent resistance and R 3 , R 2 are the individual resistances. Write the expression for the equivalent resistance in series connection. R eq = R + R 1 + r (II) Here, R eq is the total resistance and r is the internal resistance. Write the expression for Ohm’s law. V = i R eq (III) Here, V is the applied voltage and I is the current flowing in the circuit. Write the expression of current through R 3 i 3 = i R 2 R 2 + R 3 (IV) Write the Expression of voltage across resistance, R 3 . V 3 = i 3 R 3 (V) Conclusion: The Below figure represents the direction of current. Substitute 2 Ω for R 3 and 2 Ω for R 4 in Equation (I) to calculate R . R = 47 Ω × 33 Ω 47 Ω + 33 Ω = 19.3875 Ω Substitute 19.3875 Ω for R , 33 Ω for R 1 and 12.5 Ω for r in Equation (II) to calculate r p R eq = 19

Part A ■Review The uniform 150-lb stone (rectangular block) is being turned over on its side by pulling the vertical cable slowly upward until the stone begins to tip. (Figure 1) If it then falls freely (T = 0) from an essentially balanced at-rest position, determine the speed at which the corner A strikes the pad at B. The stone does not slip at its corner C as it falls. Suppose that height of the stone is L = 1.2 ft.

Consider the circuit shown in the figure. The battery has emf ε = 69 volts and negligible internal resistance. The inductance is L = 0.4 H and the resistances are R 1 = 12 Ω and R 2 = 9.0 Ω. Initially the switch S is open and no currents flow. Then the switch is closed. After leaving the switch closed for a very long time, it is opened again. Just after it is opened, what is the current in R 1?
