time constant=RC
so time constant is directly proportional to resistance.
timeconstant= (6.4/1.9)*2.6 seconds
A circuit contains a resistor in series with a capacitor, the series combination being connected across the terminals of a battery. The time constant for charging the capacitor is 2.6 s when the resistor has a resistance of 1.9 x 104 Ω. What would the time constant be if the resistance had a value of 6.4 x 104 Ω?
