The total resistance of a light bulb marked 2V and 3A is 0.67ohms
HOW TO CALCULATE RESISTANCE:
- The resistance of a substance can be calculated by using the formula as follows:
R = V/I
Where;
- R = resistance (in ohms)
- V = voltage (in volts)
- I = current (in amperes)
- According to this question, a light bulb is marked 2V and 3A. The resistance (R) can be calculated as follows:
R = 2V ÷ 3A
R = 0.67ohms.
- Therefore, the total resistance of a light bulb marked 2V and 3A is 0.67ohms.
