Following circuit has v=30v, r1=20ohm,r2=10ohm,r3=15ohm. A)Determine inductor current (I) and capacitor voltage (Vc). B)Determine power supplied by source before switch is open.
The Attempt at a Solution
I attempted to treat the load plus the capacitor as one node (v3=vc). From there I took V1 to be 30v. I set up two KCL equations and solved for V2 and v3. I got Vc=7.5 v and I=1.5 A. Then for part b, I used P=VI and got 11.25 watts. I just wanted to know of this answer is correct or not. Thanks
