What happens if capacitance of circuit is more than resistance?

Resistance is a completely different quantity to capacitance, resistance being measured in ohms and capacitance in farads. So they are 'Apples and Oranges'. You should be asking, 'What happens if capacitive reactance (in ohms) is larger than resistance?'. And one answer would be that the phase angle will be greater than 45 degrees. There are other answers, too, but it depends what you want to know,
