Qs 6b iv) The circuit will become series when switch s1 and s2 are closed. But im using this formula V=IR to calculate the current which is coming 6.25A. then im using the formula P=I2R to calculate the power. These are the values i put: P=6.25*6.25*(38.4+38.4). But my answer is coming wrong. What am i doing wrong please help me
