U-220v a-4400дж q-?

To find the charge \( q \), we can use the formula that relates potential difference (voltage), energy, and charge: \[ U = \frac{W}{q} \] where: - \( U \) is the voltage (in volts), - \( W \) is the energy (in joules), - \( q \) is the charge (in coulombs). Rearranging the formula to solve for \( q \): \[ q = \frac{W}{U} \] Now, substituting in the given values: - \( W = 4400 \text{ J} \) - \( U = 220 \text{ V} \) Substituting the values in: \[ q = \frac{4400 \text{ J}}{220 \text{ V}} = 20 \text{ C} \] So, the charge \( q \) is 20 coulombs.
