An electrical substation had a sudden discharge arc event lasting 0.005 seconds. The event produced 768,000 volts that conducted 500 amperes to a nearby grounded metal strap and opened a 500 ampere protective breaker.
(a) How much power was produced by the electrical discharge?
(b) How much energy was in the discharge?
(c) How long could a 75 watt light bulb stay lit, if all the energy in the arc was used to operate it?

Before the switch is closed, the capacitor has an initial charge go and the circuit has an initial current go- R 9(1) i(t)↓ After the switches closes, current flows through the circuit and the capacitor begins to discharge. The equation that describes the total voltage in the loop comes from Kirchoff's voltage law: L di(t) + Ri(t)+(0) = 0, (1) where i(t) and q(t) are the current and capacitor charge as a function of time, L is the inductance, R is the resistance, and C is the capacitance. Using the fact that the current equals the rate of change of the capacitor charge, and dividing by L, we can write the following homogeneous (no input source) differential equation for the charge on the capacitor: 4(1) +29(1)+w79(1)=0, ཀྱི where a= R 2L and The solution to this second order linear differential equation can be written as: 9(1) =Aent - Beat, where (3) (4) (5) A= (81+20)90 +90 (82+20)90 +90 and B= (6)…arrow_forward
