Today you are going to be practicing making predictions using the formulas we have talked about in class so far. Lets talk about the formula for momentum [p = mv]. Lets say you watched a man run and knew the mass ( m )and the velocity (V) of the man and
then calculated the momentum and your answer was p. The man then iTuns for a second time and his mass stays the same (m)
but this time his velocity was twice as fast ( 2V). What is his new momentum after the 2nd run?

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
