An RC circuit in an electronic timer is arranged therefore that a switch is activated when the potential difference across the capacitor falls to 50% of its initial value. The capacitance is 0.15 F.

Assume the switch is to be activated 30 seconds after timing begins. Compute the required value of R. (Hint: Use the relationship from (a) -- solve for R. Be careful with signs and units.).
