In the figure below, suppose the switch has been closed for a time interval sufficiently long for the capacitor to become fully charged. (Assume R₁ = 11.0 kn, R₂ = 22.0 km2, R3 = 4.00 k2, and C = 16.0 μF.) 9.00 V (a) Find the steady-state current in each resistor. I1 = I2 = 13 = ww μА JA μА (b) Find the charge Qmax on the capacitor. μC Nood Holn? I R₂< ms Dud (c) The switch is now opened at t= 0. Write an equation for the current in R₂ as a function of time. (Use the following as necessary: t. Do not enter units in your answers. Assume the current is in microamperes, and tis seconds.) IR₂ = с (d) Find the time interval required for the charge on the capacitor to fall to one-fifth its initial value. {R3

Electric field

A physical field present around an electrically charged particle that exerts a force on all other charged particles is called an electric field. The charged particles present in the field either repel or attract. From electric charges or time-varying magnetic fields, the electric field originates. One of the manifestations of electromagnetic force which is one of the four fundamental forces present in nature are the electric fields and magnetic fields.
