whatwill be the voltage on the voltmeter when (i) the capaciotr is uncharged and switch is open
(II) switch is closed and the capacitor is fully charged
b) the value of the variable ressistor is set to a low value and the capacitor is observed to take 4s to become fully charged ( voltage in circuit = 1.5v)
(I) how is it possibleto tell when the capacitor is fully charged
(II) the variable resistor is now set at its maximum resistance how will this affect the time taken for the capacitor to charge ?
(ii) the resistor is returned to tis orignal value and the capacitor is replaced with one which has a larger value of capacitance. How will this affect the time ti takes for the capacitor to become charged
