Explanation:
20 and 30 ohms connected in parallel
20 and 30 ohms connected in parallelResultant is 1/20 +1/30=5/60=1/12=12ohms
20 and 30 ohms connected in parallelResultant is 1/20 +1/30=5/60=1/12=12ohmsTotal resistance is 8+12=20 ohms
20 and 30 ohms connected in parallelResultant is 1/20 +1/30=5/60=1/12=12ohmsTotal resistance is 8+12=20 ohmsCurrent is 12/20 amps
20 and 30 ohms connected in parallelResultant is 1/20 +1/30=5/60=1/12=12ohmsTotal resistance is 8+12=20 ohmsCurrent is 12/20 ampsvoltage drop across 12 ohms is 12*12/20=144/20=7.2 volts
