Resistance

Question 1

What are the 2 fundamental elements in a circuit?

Answer 1

In each circuit, there are two fundamental elements, which are resistor and cell.

Question 2

What is the definition of resistance?

Answer 2

each conductor has a prevention towards electrical charges passing through it, which is measured by dividing the voltage across two ends of the resistor by the current passing through it.

Question 3

What is the formula of Resistance?

Answer 3

R=V/I
R= Resistance (Ohm)
V= Voltage (Volt)
I= Current (Ammeter)

Question 4

How do we measure resistance?

Answer 4

The voltage is read by voltmeter, it has to be connected in parallel, and the current is measure by an ammeter (An instrument that measures in current), it has to be connected in series.
