V0=Eas-(Ead-E0)e^-t/(TC)

find V0
given :
Eas=-75.0V
E0=-32.0V
TC=175
t=225

Solution

V_o = E_as - (E_as - E_o)e^-t/(TC)

Given E_as = -75.0V , E_o = -32.0V , t = 225 , TC = 175

==> V_o = -75 - (-75 - (-32))e^-225/175

==> V_o = -75 - (-75 + 32)e^-9/7

==> V_o = -75 - (-43)e^-9/7

==> V_o = -75 - (-11.8875)

==> V_o = -63.1125

Hence V_o = -63.1125 V
