A constant inductance of 1 henry and a variable resistance R are connected in series with a constant 1 1+t emf of E volts. If R = ohms at time t seconds and if the current is initially zero, what value of E will make the current 24 amperes after 4 seconds? (Round off to 4 decimal places and do not indicate the unit in the final answer.)
