Waec Model Questions Vol1 2021 Physics Question 4
Practice practical question 4 from the 2021 Waec Model Questions Vol1 Physics examination. This question covers Ohm's Law, Electric Circuits .
A circuit is set up to verify Ohm’s law. A variable resistor (R) is connected in series with a 2.0 Ω resistor and a 12.0 V DC supply. The voltage across the variable resistor and the current through the circuit are measured for five different settings of R as shown in the table below. | R (Ω) | V_R (V) | I (A) | |-------|---------|-------| | 2.0 | 4.8 | 0.40 | | 4.0 | 6.4 | 0.40 | | 6.0 | 7.6 | 0.40 | | 8.0 | 8.8 | 0.40 | |10.0 |10.0 | 0.40 | All readings are recorded to the nearest 0.1 V and 0.01 A.
