a spinning top has a diameter of 10cm. a ooint on the outer rim of the top moves through an angle of 8πradians each second. what is the angular velocity of the point​

The low lands i believe

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

Answermake them get very hot and over time wear them out;
