What is the amount and the date of renewal of the license?

Step 1: Total resistance $R$.

$$R = R_1 + R_2$$ $$R = 3\,\Omega + 5\,\Omega$$ $$R = 8\,\Omega$$

Step 2: Total current $I$.

$$I = \frac{U}{R}$$ $$I = \frac{12\,\text{V}}{8\,\Omega}$$ $$I = 1.5\,\text{A}$$

Step 3: Voltage across $R_1$, $U_1$.

$$U_1 = I R_1$$ $$U_1 = 1.5\,\text{A} \times 3\,\Omega$$ $$U_1 = 4.5\,\text{V}$$

Step 4: Voltage across $R_2$, $U_2$.

$$U_2 = I R_2$$ $$U_2 = 1.5\,\text{A} \times 5\,\Omega$$ $$U_2 = 7.5\,\text{V}$$

Step 5: Power dissipated in $R_1$, $P_1$.

$$P_1 = U_1 I$$ $$P_1 = 4.5\,\text{V} \times 1.5\,\text{A}$$ $$P_1 = 6.75\,\text{W}$$

Step 6: Power dissipated in $R_2$, $P_2$.

$$P_2 = U_2 I$$ $$$$
