A voltage appears between the ends of the wire. If the ends of the wire are connected, or if there is a conductor between them, then a current flows in the wire.
Answer:
Given parameters
Potential difference (V) = 220 V
Power of lamp 1 (P1) = 100 W
Power of lamp 2 (P2) = 60 W
Both the bulbs are connected in parallel. Therefore, the potential difference across each of them will be 220 V, because no division of voltage occurs in a parallel circuit.
We know that
Power = Voltage x Current
P = V x I
I = P/V
Lamp 1:
I1 = P1/V
I1 = 100/220
I1 = 5/11 A
Lamp 2:
I2 = P2/V
I2 = 60/220
I2 = 3/11 A
Net current (I) = I1 + I2
I = 5/11 + 3/11
I = 8/11
I = 0.7273 A
Hence, current drawn from the line is 0.727 A

Answer:
If the velocity and acceleration are in the same direction (both have the same sign - both positive or both negative) the object is speeding up. If the velocity and acceleration are in opposite directions (they have opposite signs), the object is slowing down.
