Which of the following is NOT a barrier to physical activity? 1. Lacks parental support or peer approval

2. Has access to all fitness and sports equipment

3. Feels exercise is boring

4. Is self conscious about exercising in front of others

When is this

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
