A transformer has negative voltage regulation when its load PF is

lagging
leading
unity
zero

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Voltage regulation = ((no load voltage)-(full load voltage)/(no load voltage))
VR at leading PF = ((I*R*cosφ)-(I*X*sinφ))/V
VR at lagging PF = ((I*R*cosφ)+(I*X*sinφ))/V
