Document Content and Description Below

What's the equation for the volume of the cylinder? V (volume)= pi multiplied by R squared multiplied by the height Example: radius is 6" height is 30 V=3.1416•6•6•30 A drill draws a c ... urrent (I) of 4.5 amps and resistance of 16.0 ohms, how do You find the power(watts)? P=I squared (amps) multipled by R(resistance) Example:P=4.5•4.5•16.0 4.5•4.5=20.25 20.25•16.0=324 P=324 What is the equation for distance? D=R•T D(distance=R(rate) multiplied by T(time) What is the equation for pressure? pressure = force/area P(pressure)= F(force) divided by A(area) What is the equation For voltage? E=I•R voltage (E) = current(I) x resistance(R) What is the equation for current or amps (i)? I=E/R i (current in Amps) R=(resistance in ohms) E(volts) What is the equation for series voltage? Et=E1=E2=E3 ET(total voltage) What is the equation for series resistance? Rt=R1+R2+R3 R=resistance What is the equation for series current? It=i1=i2=i3 it=total current in amps I=current in amps How do you calculate resistance of a wire? R=P•L/A R=resistance of the wire P= resistivity constant of the wire L=length of the wire A=cross sectional area of the wire What is the equation for parallel voltage? Et=E1=E2=E3 E=voltage ET=total voltage What is the equation for parallel current? iT=i1+i2+i3 [Show More]
