Thus, it should insert a large resistance so that the circuit is not disturbed. connected to a parallel plate capacitor with a plate area of 2 that were created by the series combinations in. ) with full confidence. Magnetic Fields. Answer (1) Hint : Parallel circuit elements have same potential difference. All NCERT textbook questions have been solved by our expert teachers. What is the new total resistance of the circuit? Solution: 1 R T 1 R 1 1 R 2 1 R 3 1 R 4 1 R T 1 4 1 8 1 16 1 4 1 R T 4 16 2 16 1 16 4 16 11 16 R T 16 11 1. If you get any. Loaded-Q The loaded Q of a resonant circuit is dependent upon three main factors: 1. Then calculate total circuit current and the voltage drops and currents. The low resistance bulb, because it draws more current. Springs--Two Springs in Parallel.
