Resistors In Parallel Diagram. In national 5 physics calculate the resistance for combinations of resistors in series and parallel. R a r b and r n are the resistances of the renal hepatic and other arteries respectively.
R4 40 ω. R 2 20 ω. The equivalent overall resistance is smaller than the smallest parallel resistor.
Consider the following circuit where four resistors r1 r2 r3 and r4 are connected in parallel.
R 2 20 ω. 1 r total 1 r a 1 r b. The resistance values of each resistor are. Use ohms law to relate resistance current and voltage.
