WebFeb 24, 2012 · Power dissipated by the resistor in the form of heat, P = I 2 R (watts). The rate at which energy is stored in inductor, So, total power in series RL circuit is given by adding the power dissipated by the resistor and the power absorbed by the inductor. Power triangle for series RL circuit is shown below, WebHow to factor expressions If you are factoring a quadratic like x^2+5x+4 you want to find two numbers that Add up to 5 Multiply together to get 4 Since 1 and 4 add up to 5 and multiply together to get 4, we can factor it like: (x+1) (x+4) Current calculator limitations Doesn't support multivariable expressions
WebIn a purely resistive circuit, all circuit power is dissipated by the resistor (s). Voltage and current are in phase with each other. In a purely reactive circuit, no circuit power is dissipated by the load (s). Rather, power is alternately absorbed from and returned to the AC source. Voltage and current are 90° out of phase with each other. WebA polynomial is an expression of the form ax^n + bx^ (n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. The zeros of a polynomial are the values of x for...
