3. Four capacitors are connected to an EMF as shown with C₂ = 20 μF, C₂ = 4μF, C₂ = 3 μF, and C₁ = 4 μF. The voltage across C₂ is 20 V. a. What is the equivalent capacitance of the circuit? Redraw circuit at each step. b. What is the EMF? You may (but do not need to) make a table similar to the first problem to help organize your calculation. B d. What is the total energy stored in the capacitors? Do it the easy way! C₁ +7 C₂ c. What would a voltmeter read if the COM lead is at A and the V lead is at B? In other words, what is Vs - V₁? CN HH C₁
