Answer:
it means an expert verified the answer so its nearly always true
Explanation:
Allowing for a platform in which the box holds potential energy
The effect of this problem is that negative particles and positive particles contract to each other caused by electrical force.
Total Current = 2 Amps
Req total = 60 ohms
Current on EF mesh = 1/3 Amp
Current on 24 ohms resistor = 1/6 Amp
Voltage on the 40ohms resistor is lefting.
