The source in the circuit in is inadvertently short-circuited at its terminals \( \mathbf{a}, \mathbf{b} \), as shown in. At the time the fault occurs, the circuit has been in operation for a long time. Suppose that \[ v=175 \mathrm{~V} \] What is the initial value of the current \( i_{\mathrm{ab}} \) in the short-circuit connection between terminals a, b? Express your answer to three significant figures and include the appropriate units. What is the final value of the current \( i_{\mathrm{ab}} \) ? Express your answer to three significant figures and include the appropriate units. How many microseconds after the short circuit has occurred is the current in the short equal to \( 19 \mathrm{~A} \) ? Express your answer in microseconds to three significant figures.
