HELP PLEASE !! I DONT UNDERSTAND
an electric circuit, the resistance
(R ohms) of a component may be
V across the component and I is the calculated using the formula R = V/I, where V is the potential difference current through the component. The potential difference is measured as 6 V to the nearest volt, and the current is measured as 0.2 A to the nearest tenth of an ampere.
a. Calc lower and upper bounds for the resistance
b. Actual value of the resistor is 30 Q. Calculate the maximum possible percentage error that could be obtained.
