Pylon cables in the National Grid have some resistance. Power (watts) = Current2 (amperes) x Resistance (ohms) Looking at the power equation above, can you explain why transmitting electricity at a very high voltage is beneficial? Hint: Think about the equation Power (W) = P. D (V) x Current (A) Equation
