Instructions As a review of Ohm's Law, please play around with the below PhET simulation. What happens to the current (I) when you change the voltage (V)? And when you change the resistance (R)? To receive credit for this activity, answer the questions that follow. Preview V- R V R vollage resistance 1.5V 1.5V 1.5V current = 9.0 mA 4.5 V 500 0 Ohm's Law 4) PhET : Question 1 Holding resistance constant, double the voltage. What happens to the current as a result? current doubles current reduces by half current remains unchanged Question 2 Holding voltage constant, double the resistance. What happens to the current as a result? current doubles current reduces by half current goes unchanged Question 3 Double both the voltage and resistance. What happens to the current as a result? current doubles current is reduced by half current remains unchanged Question 4 Double the voltage and reduce the half. What happens to the current as a result? current doubles current is reduced by half current remains unchanged current is quadrupled current is reduced to one quarter its initial value Question 5 Double the resistance and reduce the voltage by half. What happens to the current as a result? current is doubled current is reduced by half current remains unchanged current is quadrupled current is reduced to one quarter its initial value
