what symbol is used instead of writing charge
Q
How are potential difference and current related when resistance is constant?
Directly proportional or as potential difference increase, current increases
state the equation linking potential difference,charge and energy using words
Energy= charge x potential difference
state the equation linking potential difference, current and resistance using words
potential difference= current x resistance
How do we check that 2 variables are directly proportional
Divide the variables at least 3 times. Answer should be the same every tine
How are resistance and current related when potential difference is constant?
Inversely proportionally OR as resistance increases, current decreases
