PHYC 240-EXAM 3-Practice Problems 3) A 2.00 nF capacitor is charged with a 60.0 V battery. The battery is then removed The charged capacitor is then attached to a 2000.0 ohm resistor at t -o. a) What is the time constant? b) How long until the the charge drops to 20% of its original value? You have an extra 2000.0 ohm resistor. How would you add it to the circuit to reduce the time constant by one half? Draw the...
vullements > Healer Question for exam 3 Healer Question for exam 3 Thomas Fleming All Sections A series RLC circuit consists of a 40 pF capacitor, a 1.5 Hinductor, and a 100 Ohm resistor connected to a battery which outputs a 120 Volt rms potential at a frequency of 60 Hz. Determine: 1. The impedance of the circuit 2. The rms current carried by the circuit. 3. Does the current lag or lead the voltage? Show your work. 4. What...

please answer all questions Phys 212 Tutorial 11 Electromagnetic Inductions and Inductor Circuits Name: ! O Q1 Five loops are formed of copper wire of the same gauge (same cross-sectional area). Loops 1-4 are identical; loop 5 has the same height as the others but is longer. At the instant shown, all the loops are moving at the same speed in the directions indicated There is a uniform magnetic field pointing out of the page in Region I; in Region...
