Please answer the question

A charged capacitor is connected to a resistor and a switch as in the figure below. The circuit has a time constant of 2.45 s. Soon after the switch is closed, the charge on the capacitor is 50.0% of its initial charge. + Q те R (a) Find the time interval required for the capacitor to reach this charge. S (b) If R = 230 k, what is the value of C? C = μF

A certain car battery with a 12.0 V emf has an initial charge of 136 A · h. Assuming that the potential across the terminals stays constant until the battery is completely discharged, for how many hours can it deliver energy at the rate of 130 W? _______________h (please show units when you work this out so that I can follow it easier.)

A student in the laboratory connects a 17 Ω resistor, a 26 Ω resistor, and a 34 Ω resistor in parallel and then connects the arrangement to a 46 V dc source. (a) What is the current? A(b) What is the power? W

You take a 6.34 V battery, a 226 kQ resistor, and an uncharged capacitor to put together a series circuit. You connect the battery and after 21.2 seconds the current in the circuit has fallen to 61% of its initial value. What is the value of the capacitor in microfarads (µF)? (Enter answer as an integer.
