Explanation :
A circuit is the representation of the path of the flow of current. The circuit can be either closed or open.
When the switch is off the circuit is closed circuit and when the switch is not connected the circuit is open.
The items that are sufficient to make a circuit are as follows :
- Voltage source like a battery.
- Resistors or electrical equipment like heater, motor etc.
Other components can be ammeter, voltmeter, ac source, variable resistors etc.
For this case we have to, by definition:
Where:
v: It's the velocity
x: It is the distance traveled
t: It is the time spent
1 hour equals 60 minutes and 1 minute equals 60 seconds.
On the other hand:
1 kilometer equals 1000 meters
So:
On the other hand:
