The statements in the following list all refer to a circuit consisting of a capacitor, initially charged by a battery, and a resistor. At time t = 0, the capacitor is discharged through the resistor by the closing of a switch. Check the boxes of the THREE TRUE statements. 01. The charge stored on the capacitor follows a similar variation with time to the variation of the current. 2. After 3 time constants, the power stored on the capacitor will have decayed by a factor of (1/e) 5. 3. The rate of decrease of charge stored on the capacitor will increase as the time increases. 4. The time constant has units of time and is equal to the time taken for the current to fall to 1/e of its final value. 5. A common form of capacitor is a cylindrical shape formed by rolling a metallic foil and a thin dielectric in a 'sandwich' into a cylindrical shape. 6. The quantity &, relative permittivity, is a measure of the factor by which the capacitance of a capacitor is increased by the introduction of a…
For each of the three simple circuit boards you will need to calculate the total resistance Reg for the entire circuit board by using the measured resistances of each of the resistors, and the equations given to you in the theory section. Then using the applied voltage of 2V, as the theoretical voltage Vth for the entire circuit board you can calculate the theoretical current, ith, for the entire circuit board.

From Ohm's law, we arrive at a general formula for current: Plugging in values, the current across the resistor R1 is equal to: (Please note that the current is milliamperes) Similarly the current across R2 is: 12= mA And the current across R3 is: 13 = mA The current read by the ammeter is the sum of the currents across each resistor: 1=h+/2 +13 |= Alternatively, we can solve for the current across the ammeter by first calculating the equivalent resistance and then applying Ohm's law.
