# A heating element with constant resistance \(R\) dissipates electrical power \(P_0\) when connected across a potential difference \(V_0\). The potential difference across the heating element is then increased to \(2V_0\). What is the new electrical power dissipated by the heating element?

A heating element with constant resistance \(R\) dissipates electrical power \(P_0\) when connected across a potential difference \(V_0\). The potential difference across the heating element is then increased to \(2V_0\). What is the new electrical power dissipated by the heating element?

- **A.** \(4P_0\)
- **B.** \(2P_0\)
- **C.** \(\sqrt{2}P_0\)
- **D.** \(\dfrac{1}{2}P_0\)
