A 34.5 KV STATION HAS A SHORT CIRCUIT IMPEDANCE OF AT GIVEN POINT OF O.21 PU BASE ON 100MVA  DETERMINE THE INTERRUTING CAPACITY OF THE CURCUIT BREAKER NEEDED

Why do we not use a current divider with the 1 ohm resistor and -j1 capacitor when finding I1?

a resistor and and capacitor are connected in parallel to a 277 v 60 hz power source. the resistor has a value of 50 ohms and the capacitor has a value of 40 uf what is the circuit power factor.

A 15-F AC capacitor is connected in series with a 50 resistor. The capacitor has a voltage rating of 600 WVDC. The capacitor and resistor are connected to a 480-V, 60-Hz circuit. Is the voltage rating of the capacitor sufficient for this connection?

arcing c

a capacitor and a resistor are connected in parellel to a 120 v 60 hz line the resistor has a resistance of 40 ohms and the capacitor has a capacitance of 132.6 uf what is the total current flow through the circuit. what is the impedence and the power factor and how many degrees out of phase are the current and voltage out phase with eachother.

Consider the RC circuit in Figure 2 below. Assuming the switch has been open for a long time before it is closed, fill in a table providing the current through each component and the voltage across each component immediately after the switch is closed, and a very long time after the switch is closed. Next, figure out the time constant for the circuit. (Hint: Assign currents to each branch. Set up the necessary KVL and KCL equations. Eliminate all but one variable to get an equation for just one of the currents. You shouldn’t have to solve this equation to recognize the time constant!)

55. What determines the exact amount of phase angle difference in a resistive-capacitive series circuit? a. ratio of voltage to capacitance - b. ratio of resistance to capacitance c. ratio of reactance to resistance d. ratio of capacitance to resistance

Because alternating current starts at zero, reaches a peak, and then returns to zero, there is always a variation in voltage and an effective value has to be determined. Select one: TRUE FALSE
