GM describes their brand politics as having "two brands" which "will drive our global growth. They are Chevrolet‚ which embodies the qualities of value‚ reliability‚ performance and expressive design; and Cadillac‚ which creates luxury vehicles that are provocative and powerful. At the same time‚ the Holden‚ Buick‚ GMC‚ Baojun‚ Opel and Vauxhall brands are being carefully cultivated to satisfy as many customers as possible in select regions.

5.7 Necessity of D.C. Motor Starter At starting‚ when the motor is stationary‚ there is no back e.m.f. in the armature. Consequently‚ if the motor is directly switched on to the mains‚ the armature will draw a heavy current (Ia = V/Ra) because of small armature resistance. As an example‚ 5 H.P.‚ 220 V shunt motor has a full-load current of 20 A and an armature resistance of about 0.5 . If this motor is directly switched on to supply‚ it would take an armature current of 220/0.5 = 440 A which

Introduction and Objective The action potential is an impulse of electrical activity. Action potential occurs when a neuron sends messages electrochemically down an axon called a nerve impulse. When a neuron is not stimulated or inactive‚ it is at resting potential. When a neuron is at rest‚ the electrical charge on the inside of the neuron is negative while the electrical charge on the outside of the neuron is positive. The resting membrane potential of a neuron is about -70 mV (mV = millivolts)

The electric shock generator had a row of switches marked from 15 to 450 volts in 15 volt increments with adjectives describing how severe the shock was‚ and 435 and 450 volts were labelled “XXX”.
