Two voltage sources are connected to a circuit. At tim(89 surt2k+ 40bnxm*htp jnxsoby, n*e t milliseconds (ms)fddw 8txbi/ x.3q0r; v, the voltage from the first source i;r 0/ix w3d8.vbfdq txs $V_1$(t)=12cos(20t) and the voltage from the second source is $V_2$(t)=18cos(20t+5), where both $V_1$(t) and $V_2$(t) are measured in volts.
1.Write, in the form V(t)=Acos(ωt+φ), an expression for the total voltage in the circuit at time t ms.
2.Hence write down the highest voltage in the circuit.
