Question

Kaya collects the data shown in the table.

Answer 1

Answer : The resistance in the circuit is $20\ \Omega$

Explanation :

The given data shows the resistance and the current flowing in the circuit.

Voltage, V = 6 V

Current flowing, I = 0.3 A

The ohms law gives the relationship between the current flowing, the voltage and the resistance in the circuit.

Mathematically, it is written as :

$V=IR$

$R=\dfrac{V}{I}$

$R=\dfrac{6\ V}{0.3\ A}$

$R=20\ \Omega$

So, the correct option is (D).

Hence, this is the required solution.          

Answer 2

Answer;

= 20 ohms

Explanation;

• According to the Ohm's law, the current through a conductor is directly proportional to the potential difference if other environment conditions are kept constant.

Therefore; I α V

Hence; V = IR, where R is the constant, called the resistance

Therefore; R = V/I

                  R = 6.0 /0.3

                      = 20 Ohms
