Question

A half wave rectifier supplies 100ma current to a 250 ohm load.Its dc output voltage is?

Answer 1

hello...
♪＼(*＾▽＾*)／＼(*＾▽＾*)／
mA = milliAmperes, 

d.c. = direct current, 

PIV = Peak Inverse Voltage 

ohm = electrical flow

r.m.s = root mean square 

For DC systems
current (R = V/I)

inDC system,
R (resistance) =
Z (impedance)
Z = V/I. 

250ohm = V/100mA 
V (volts) is represented voltage with the variable E,

E: 250ohm x 100mA = E 

Convert mA to A by dividing by 1000. 


250ohm x .1A = E 

E = 25 V 

thank you ☺
