If capacitors are connected in PARALLEL their combined capacities is ______________ the sum of their individual capacities Equal to POWER is measured in Watts The COMBINED resistance of two 100 ohms resistors connected in a parallel would equal 50 ohms Ohms law can be MATHEMATICALLY expressed in which equation E=I(R) JIC symbol (rectangular figure) represents Rheostat The 4th color band on a resistor is SILVER, the measured value of resistance is within________ of the marked value 10%

Electric charge A fundamental property of matter that can be either positive or negative Induced charge Static charge caused by the presence of an already charged object Coulomb's law Inverse square law, Electric Force = F = k * (q₁q₂)/r² = 1/(4πε₀) * (q₁q₂)/r Electrostatic force Force between electrically charged objects. Electric field Force that a source charge would exert on a positive test charge q₀ within its proximity divided by that test charge; E = F/q₀ ...

Electricity and Magnetism Practise guide 1) An ac source of period T and maximum voltage V is connected to a single unknown ideal element that is either a resistor, and inductor, or a capacitor. At time t = 0 the voltage is zero. At time t = T/4 the current in the unknown element is equal to zero, and at time t = T/2 the current is I = -Imax, where Imax is the current amplitude. What is the unknown element? A) a resistor B) an inductor C) a capacitor D) an inductor or a capacitor Answer: C ...
