ABSTRACT
The total resistance, RT , of resistors R1, R2 and R3 connected in series is given by
RT = R1 + R2 + R3 This is an algebraic equation. If R1 = 6.3k, R2 = 2.4k and R3 = 8.5k, then
RT = 6.3+ 2.4+ 8.5 = 17.2k The temperature in Fahrenheit, F , is given by
F = 9 5 C + 32
where C is ∗. This is an algebraic If C = 100◦C, then F = 9
5 × 100+ 32
= 180+ 32 = 212◦F. If you can cope with evaluating formulae then you will be able to cope with algebra.
