Point2. The potential differenceacross the terminals of aresistor of 5 ohm, having 2000C charge flowing in 200seconds isO 45 VO 50 VO 100 VO 75V |

Answer» is ϕ ahead of i because i and R is in phase and i.e., −Z and ε are in phase as ε=ε 0
sinwt from diagram i= −Z ε 0
sin(ωt−ϕ) where, ϕ=tan −1
R X
b) i=1.0A (given) V R
=160V=iR⇒R= 1 160
=160 V L
=120V=iX L
⇒X L
= 1 120
=120 V net
= V R 2
+V L 2
= (160) 2 +(120) 2
= 25600+14400
=200 : EFFECTIVE value of apphed VOLTAGE Z= R 2 +X L 2
= (160) 2 +(120) 2
=200 : Impedence Explanation: please mark me as brainliest |
